After 66k miles my odometer finally stopped working. I have the cluster out and new gear in hand. My problem is I removed the 4 screws on the white backing plate but I cannot remove it from the speedo. I want to replace the gear without removing the needle .Do the 2 small screws on the speedo have to come out anyway? I tried to pry the back off but stopped before I did something wrong. The car is an 89 240DL. What am I doing wrong?I checked D.B's page but says nothing about a stuck back plate. Thanks
